For some reason, I can't get the IDE to compile BOOST_MPL_ASSERT. I tried this: #include <boost/type_traits/is_same.hpp> #include <boost/mpl/assert.hpp> int main() { BOOST_MPL_ASSERT(( boost::is_same< char, char > )); } and it gives the following errors: d:\dev\boost.cvs\boost\libs\fusion\example\extension\test_example.cpp(31) : error C2143: syntax error : missing ';' before '=' d:\dev\boost.cvs\boost\libs\fusion\example\extension\test_example.cpp(31) : error C2143: syntax error : missing ';' before '=' what's even stranger is that i copied/pasted the pre-processed file, and that compiled just fine: static const std::size_t mpl_assertion_in_line_26 = sizeof( boost::mpl::assertion_failed<false>( boost::mpl::assert_arg( (void (*) ( boost::is_same< char, char > ))0, 1 ) ) ); anyone else seen something like this before?? all the mpl regression tests compile fine via bjam (using msvc 7.1), so it appears ide-specific, somehow... thanks, --craig ____________________________________________________________________________________ Do you Yahoo!?
